I have purchased an OS 3.0 DC a few days ago and now I am facing serious trouble setting up the system!

What I have done so far:
Power the board with an external USB Power Supply
connected my Laptop via WiFi to the OS 3.0, IP Address 192.168.4.1
Open Google Chrome, (also tried Firefox, etc) entered Proper SSID and pwd
Button goes from ‘Submit’ to ‘Connecting’
OS Board shows ‘Connecting’ as well – but nothing else happens! What I understand from the instruction the board should reboot and switch into the Client mode, but that never happens! Did I miss anything in between? When I press the B1 Button I can see as IP only 0.0.0.0 as Ip and 80 for the port – for me no valid IP…

I tried to reset the board several time but with the same result as before…
